FRUIT JAR WRENCH- Filed July l0, 1955 ZZo ATTORNEY Patented June 3G, 1936 UNITED STATES PATENT OFFICE FRUIT JAR WRENCH Otto Kielman, Waukegan, Ill.

Application July 10, 1935, Serial No. 30,695

3 Claims. (Cl. 81-3.1)

The invention relates to a wrench and more especially to a jar wrench.

The primary object of the invention is the provision of a wrench of this character, wherein the same when clamped about the cover or cap of a fruit jar will firmly grip it for its easy removal, particularly when the cap or cover is screwed upon the jar and held fast thereon, the Wrench in its entirety being of novel construction.

Another object of the invention is the provision of a wrench of this character, wherein the same is readily applied to and removed from the cover or cap of a jar such as a fruit jar and when applied will assure a tight grip thereon so that the cap or cover can be conveniently removed without excessive labor on the part of the operator of the wrench.

A further object of the invention is the provision of a Wrench of this character, which is simple in construction, thoroughly reliable and efficient in its operation, involving but few parts, these being assembled in a unique manner, strong, durable, assuring a tight fit and inexpensive to manufacture.

With these and other objects in view, the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawing, which discloses the preferred embodiment of the invention and pointed out in the claims hereunto appended.

In the accompanying drawing:

Figure 1 is a top plan view of the wrench constructed in accordance with the invention.

Figure 2 is a fragmentary side elevation of a fruit jar with a cap fitted thereon and showing the wrench applied.

Figure 3 is a sectional view on the line 3-3 of Figure 1 looking in the direction of the arrows.

Similar reference characters indicate correspending parts throughout the several views in the drawing.

Referring to the drawing in detail, A designates a portion of the body of a fruit jar of standard kind having a screw threaded cap or cover B as usual while C designates generally the wrench constituting the present invention and hereinafter fully described.

The wrench C comprises an open ring 5 preferably made from inherently springy wire having the required strength and durability and at the open side of said ring are the outwardly diverging normally spread arms 6, these constituting the handles for the wrench and are integral with the ring 5.

Bent from the arms 6 are the inwardly folded convergent extensions 1 terminating at the opening in the ring 5 with gripping jaws 8 having the reversely beveled tips or terminals 9. The jaws 8 are curved at their working faces I0 corresponding to the curvature of the ring 5.

Fitted between the arms 6 and the extensions 'i in close proximity to the jaws 8 are cross struts Il, these having seats l2 for the said arms and extensions and are welded or otherwise lxedly 15 secured at I3 in place so as to guide the jaws 8 in clamping position when pressure is applied to the arms 6 which constitute the handles of the wrench so that when the ring embraces the cap or cover B, these jaws 8 will be pressed tightly 20 against the cap or cover for a rm grip of the same thereby so that by the turning of the wrench the cap or cover B can be tightly screwed onto the jar or unscrewed therefrom.

The ring 5 is normally spread to have a di- 25 ameter greater than the diameter of the cap or cover B and such ring is susceptible of contraction and expansion and under expansion thereof it can be fitted about different sizes of caps or covers for jars.

When the handles are moved toward each other and the ring 5 embraces a cap or cover a rm gripping action thereon is assured by the jaws 8 so that the wrench can be manipulated for the purposes previously stated.

What is claimed is:

1. A wrench of the kind described comprising a springy ring open at one side, arms joined with the ring at the open side, extensions bent from Y the arms and disposed in inwardly convergent 40 relation to each other between said arms, and jaws laterally bent from the extensions to lie at the open side of said ring and having curved working faces corresponding to the curvature of the ring.

j 2. A wrench of the kind described comprising a springy ring open at one side, arms joined with the ring at the open side, extensions bent from the arms and disposed in inwardly convergent relation to each other between said arms, and 50 i Yjaws vlateiailry bent from the extensionsY torlie Vat the open side of said ring and having curved workV- ingV faces corresponding to the curvatureV of the ring, the said jawsbeing formedwithY reversely the arms and disposed in inwardly convergent relation to each other'between said arms, jaws Vlaterally bent from the extensionstovr lie at'the open sideof said ringfand having curved working faces corresponding to the curvature of the VVring, the said jaws being formed withrreversely Y' Y beveled free terminals, and struts fitted between f the arms and said extensions close to said jaws.
